Image corruption on Desktop with G400Max

[iKaPoS]

I have a G400Max on my PIII 600 system. It is giving me a corrupted image on the windows desktop.
I get rows of yellow or red lnes across my screen horizontally.
This only seems to happen in windows or applications where there is blank space (ie no actual icons/images).

I have unistalled and reinstalled PD 5.52 but this still happens.

This should be in the matrox hardware forum -I'll move it over
